Time Machine won't back up. Says system date and time are incorrect.

I replaced hard drive and PRAM battery. I reinstalled OS X then when I set date and time during initial set up. The date and time displayed in the upper corner are correct. I have never used Time Machine before so I don't know if it worked before I replaced hard drive and battery.

Mac mini, Mac OS 9.0.x

If you have more than one user account, these instructions must be carried out as an administrator.

Launch the Console application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select

View Show Log List

from the menu bar.


Enter the word "Starting" (without the quotes) in the String Matching text field. You should now see log messages with the words "Starting * backup," where * represents any of the words "automatic," "manual," or "standard." Note the timestamp of the last such message that corresponds to an abnormal backup. Now

CLEAR THE WORD "Starting" FROM THE TEXT FIELD

so that all messages are showning, and scroll back in the log to the time you noted. Select the messages timestamped from then until the end of the backup, or the end of the log if that's not clear. Copy them to the Clipboard by pressing the key combination command-C. Paste (command-V) into a reply to this message.

If all you see are messages that contain the word "Starting," you didn't clear the text field.

If there are runs of repeated messages, post only one example of each. Don't post many repetitions of the same message.

When posting a log extract, be selective. Don't post more than is requested.

Please do not indiscriminately dump thousands of lines from the log into this discussion.

I ran into this issue as well. Now that this is the first entry in my google search result. I will post the solution here.


In the log:


com.apple.backupd[332]: Not starting automatic Time Machine backup: System clock is wrong.

com.apple.backupd[332]: Backup failed with error 33: 33


With the error code, I found this post:


http://superuser.com/questions/665721/time-machine-backup-failed-with-error-33


Basically,


"Time Machine is powered by a system utility called backupd. For some reason when I installed the OS, the Created & Modified dates for backupd were set in the future relative to the current date. Before TM runs there are some checks to ensure everything is in order, and if backupd was created in the future relative to the current date, it fails."


To solve this, run the following command in terminal:


sudo touch /System/Library/CoreServices/backupd

Time Machine won't back up. Says system date and time are incorrect.
